As the species is unique in my collection I have not been abb 

 to examine the antennae under a microscope, but I am almost 

 sure that there are only three joints in the stipes. 



North Queensland. 

 .4. opaculns, sp. nov. Ovatus : sat opacus ; piceo-niger, an- 

 tennis (clava excepta) palpis et elytris (nonnullorum 

 exemplorum) plus minusve rufescentibus ; pilis subtilibus 

 pallidis adpressis minus crebre vestitus ; antennis 9-arti- 

 culatis ; clypeo antice breviter tridentato, cum fronte (hac 

 minus convexa) subtiliter granulato ; prothoraoe fortiter 

 transverso, antice angustato, supra aequali, sparsim 

 granulato-punctulato, lateribus arcuatis ; elytris crebre 

 subseriatim minus fortiter granulato-punctulatis, minus 

 perspicue bicostulatis ; propygidio sat crebre, pygidio 

 minus crebre, squamoso-punctulatis ; tibiis anticis ut ^4. 

 funerei, Blackb., dentatis. 

 Maris quam feminae antennarum clava magis elongata, tibi- 

 arum anticarum dentibus minoribus, tarsis anticis crassi- 

 oribus, posticorum articulo 2" quam basalis minus quam 

 duplo longiori. 

 Feminge pygidio longitudinaliter impresso ; tarsorum posti- 

 corum articulo 2" quam basalis duplo longiori. Long., 

 U-2 1 ; lat., i-1 1. 



Its opaque dorsal surface distinguishes this species from 

 all the preceding. It is near A. (C aid ohms) evanesceiis, 

 Blackb., from which the form of its clypeus readily separates 

 it. The female has a small nitid sexual area on the subapical 

 callus. 



Western Australia (Perth). 

 .4. irrasus, sp. nov. Ovatus; subnitidus : rufus, antennarum 

 clava capite prothorace sternisque plus minusve infus- 

 catis ; pilis pallidis (his supra brevibus erectis confer- 

 tim positis, snbtus longioribus minus crebre positis) vesti- 

 tus ; antennis 8-articulatis ; clypeo antice subtruncato (vix 

 subemarginato), sat reflexo, cum fronte (hac convexa) 

 pronotoque crebre minus subtiliter subrugulose punctu- 

 lato : prothorace sat transverso, antice angfustato, supra 

 gequali. lateribus sat arcuatis : elytris obsoletissime striatis, 

 confertim subseriatim nee profunde nee subtiliter punc- 

 tulatis, haud costulatis : propygidio pygidioque fere ut 

 pronotum (sed paullo minus crebre) punctulatis : tibiis 

 anticis ut .4. funerei, Blackb., dentatis; tarsis anticis 

 brevibus. 

 Maris quam feminae antennarum clava masfis elongata, tarsis 

 anticis paullo longioribus, posticorum articulo 2" quam 

 basalis minus quam duplo longiori.
